How to Differentiate Dermatitis/Eczema from Fungal Infections (Tinea)
Disease description:
I started feeling intense itching on my hand yesterday afternoon, accompanied by some redness. I suspect it might be dermatitis or eczema, but it also seems somewhat like ringworm. How exactly can one distinguish between dermatitis/eczema and ringworm?

Dermatitis, eczema, and ringworm (tinea) exhibit significant differences in their causes, symptoms, and contagiousness, which can be used for differentiation:
1. **Dermatitis**: Primarily caused by allergic reactions, it is non-contagious. Symptoms include inflammatory manifestations such as redness, blisters, and intense itching.
2. **Eczema**: Associated with genetic and environmental factors, eczema is not clearly contagious. Its symptoms are varied and may include dry skin, redness, oozing, and significant itching. Eczema tends to recur frequently, and its resolution time is unpredictable.
3. **Ringworm (Tinea)**: Caused by fungal infection, it is contagious and can spread through contact. Symptoms include round or oval-shaped scaly patches on the skin accompanied by itching.
